Hornsea Project One

Sarens loads out four wind farm jackets at quay in Cádiz,
Spain

On the North Sea off the coast of England, an ambitious project
is currently in the works: the construction of the world's largest
wind farm, the Hornsea Project One. Once complete in 2020, the
wind farm's 174 turbines will generate enough electricity to power
over a million homes.

Sarens' client Dragados Offshore received a contract from Ørsted
A/S (formerly DONG Energy) to deliver four substation jackets
to the wind farm, some 120km off England's coast. In March of
2018, Dragados asked Sarens to load out each of the four jackets at
the quay in Cádiz, Spain.

For this operation, six Sarens crewmembers carried out the
weighing of each jacket, transport to the quay, and the final load
out. (You can view the video of the operation
here).

With the average weight of each jacket at about 1.900t and
a height of 60m, this was no small feat. The main challenge Sarens
faced was carrying out the operation while compensating for the
changing tides, which required perfect
coordination.

The team used the following equipment for the
operation:

72 axles lines for SPMT

16 load cells of 200T

28 pumps of 600T

"We are pleased with the performance of Sarens," a
representative from Dragados Offshore stated. "Different
stages of the project for each jacket were carried out with no
mistakes during weighing with the load cells, transport,
ballasting, and setting down the jackets on the grillage the first
time."
